Human factors

A scientific discipline concerned with understanding how humans interact with elements of a system. It can also be considered the practice of designing products, systems or processes to take account of the interaction between them and their users. It is also known as comfort design, functional design and user

Human information processing system

An automatic system that a person uses to interpret information and react. It is normally comprised of inputs, processes (which can be sensory, central and motor), and outputs.

Interval data

Based on numeric scales in which we know the order and the exact difference between the values. Organized into even divisions or intervals, and intervals are of equal size.

Nominal data scale

Nominal means 'by name' and used in classification or division of objects into discrete groups. Each of which is identified with a name e.g. category of cars, and the scale does not provide any measurement within or between categories.

Ordinal data

A statistical data type that exists on an arbitrary numerical scale where the exact numerical value has no significance other than to rank a set of data points. Deals with the order or position of items such as words, letters, symbols or numbers arranged in a hierarchical order. Quantitative assessment cannot be made.

Percentile range

That proportion of a population with a dimension at or less than a given value. For a given demographic (gender, race, age), the 50th percentile is the average.

Perception

The way in which something is regarded, understood or interpreted.

Physiological factor data

Human factor data related to physical characteristics used to optimize the user's safety, health, comfort and performance

Primary data

Data collected by a user for a specific purpose.

Psychological factor data

Human factor data related to psychological interpretations caused by light, smell, sound, taste, temperature and texture.

Qualitative data

Typically descriptive data used to find out in depth the way people think or feel

Quantitative data

Data that can be measured and recorded using numbers. Examples include height, shoe size, and fingernail length.

Range of sizes

A selection of sizes a product is made in that caters for the majority of a market.

Ratio data scale

Allows you to compare differences between numbers. For example, use a rating scale of 1

Reach

A range that a person can stretch to touch or grasp an object from a specified position.

Secondary data

Data collected by someone other than the user.

Static data

Human body measurements when the subject is still.

Structural data

Refers to measurements taken while the subject is in a fixed or standard position, e.g. height, arm length.

Workplace environmental factors

These factors can be considered to maximise performance of a user in a role and reduce the risk of accidents. They can be categorised as: • Management (policies, safety education) • Physical environment (noise, temperature, pollutants, trip hazards, signage) • Equipment design (controls, visibility, hazards, warnings, safety guards) • The nature of the job (repetitiveness, mental or physical workload, force, pressure) • Social or psychological environment (Social group, morale) • The worker (personal ability, alertness, age, fatigue)

Circular economy

An economy model in which resources remain in use for as long as possible, from which maximum value is extracted while in use, and the products and materials are recovered and regenerated at the end of the product life cycle.

Clean technology

Products, services or processes that reduce waste and require the minimum amount of non-renewable resources.

Combined Heat and Power (CHP)

A system that simultaneously generates heat and electricity from either the combustion of fuel, or a solar heat collector.

Converging technologies

The synergistic merging of nanotechnology, biotechnology, information and communication technologies and cognitive science.

Cradle to cradle

A design philosophy that aims to eliminate waste from the production, use and disposal of a product. It centres on products which are made to be made again.

Cradle to grave

A design philosophy that considers the environmental effects of a product all of the way from manufacture to disposal.

Dematerialization

The reduction of total material and energy throughput of any product and service.

Design for the environment software

Software that allows designers to perform Life cycle analysis (LCA) on a product and assess its environmental impact.

Embodied energy

A design strategy that focusses on three broad environmental categories - materials, energy, and pollution/waste.

End-of-pipe technologies

Technology that is used to reduce pollutants and waste at the end of a process.

Embodied energy

The total energy required to produce a product.

Energy distribution

The method with which energy is transported from a source to where it is used.

Energy storage

The method with which energy is stored for later use.

Energy utilization

The method with which energy is used.

Green design

Designing in a way that takes account of the environmental impact of the product throughout its life.

Green legislation

Laws and regulations that are based on conservation and sustainability principles, followed by designers and manufacturers when creating green products.

Incremental solutions

Products which are improved and developed over time leading to new versions and generations.

Individual energy generation

The ability of an individual to use devices to create small amounts of energy to run low

Laws considered collectively to address a certain topic.

Life cycle analysis (LCA)

The assessment of the effect a product has on the environment through five stages of its life: pre-production; production; distribution

(including packaging; utilization; and disposal.

Linear economy

An economy based on the make, use, dispose model.

Local combined heat and power (CHP)

CHP plants that generate heat and power for a local community

National and international grid systems

An electrical supply distribution network that can be national or international. International grids allow electricity generated in one country to be used in another.

Also known as the product life cycle, it is a cycle that every product goes through from introduction to withdrawal or discontinuation.

The processes of separating the component parts of a product to recover the parts and materials.

Quantification of carbon emissions

Defining numerically the carbon emissions generated by a particular product

Radical solutions

Where a completely new product is devised by going back to the roots of a problem and thinking about a solution in a different way. Recondition Rebuilding a product so that it is in an “as new” condition, and is generally used in the context of car engines and tyres.

Recovery of raw materials

Strategies for the separation of components of a product in order to recover raw materials.

Recycle

Refers to using the materials from obsolete products to create other products.

Re-engineer

To redesign components or products to improve their characteristics or performance.

The stock or supply of materials that are available in a given context.

Re-use

Reuse of a product in the same context or in a different context.
